Serilog.Sinks.MemorySink 0.1.0-alpha

🧵 Serilog.Sinks.MemorySink

A Serilog sink that store log events in memory. You can retrieve these logs and render them in your own log viewer.

The sample app shows how to create a simple log viewer using WinUI 3.

✨Getting started

Install Serilog.Sinks.MemorySink:

dotnet add package Serilog.Sinks.MemorySink

Create a logger configuration:

Log.Logger = new LoggerConfiguration()
    .WriteTo.MemorySink(out ILogSource<Serilog.Events.LogEvent> logSource)
    .CreateLogger();

Retrieve logs:

var logs = await logSource.GetLogs(startIndex, count, cancellationToken);

⚙️Custom log item, options and exception handling

To use a custom log item, you need to provide a log event converter:

public record LogItem(DateTimeOffset Timestamp, LogEventLevel Level, string Message);

Log.Logger = new LoggerConfiguration()
    .WriteTo.MemorySink(
        out ILogSource<LogItem> logSource,
        options =>
        {
            options.LogEventConverter = logEvent =>
            {
                return new LogItem(logEvent.Timestamp, logEvent.Level, logEvent.MessageTemplate.Text);
            };
            options.MaxLogsCount = 100_000;
            options.OnException = ex =>
            {
                // Handle sink processing exception.
            };
        })
        .CreateLogger();
